Structural design and simulation verification of experimental platform for infrared and hot air collaborative heating

Abstract:

The experimental study of infrared radiation and hot air collaborative heating of asphalt pavement was conducted, and the influence of coupling of different heating factors on the effect of road heating was analyzed. On the basis of analyzing the mechanism of collaborative heating on asphalt pavement and considering the specific requirements of the experiment, an experimental platform was designed and a simulation model of collaborative heating of asphalt pavement and experimental platform was established. With the aid of CFD simulation software for simulation analysis, the structural design and heating performance simulation analysis of the collaborative heating experimental platform were carried out. Results showed that the designed experimental platform could evenly distribute the hot air within the heating distance and wind speed range required for the collaborative heating experiment. The collaborative heating plate could evenly heat the road surface when the heating distance was adjusted. The hot air generator could continuously provide hot air with stable and controllable temperature and wind speed for the heating experiment. The results verified that the heating performance of the experimental platform meets the requirements of the collaborative heating experiment under multi-factor coupling, which provides a theoretical basis for the design and manufacture of collaborative heating experimental platform and the development of the collaborative heating device for thermal regeneration of asphalt pavement in the future.
